Dams can cause several types of pollution, primarily through the alteration of water quality and ecosystem disruption. They can lead to nutrient loading, which promotes algal blooms, and the accumulation of harmful substances like heavy metals and pesticides in stagnant water. Additionally, the decomposition of organic material in reservoirs can produce methane, a potent greenhouse gas. The alteration of natural water flow can also impact sediment transport, affecting aquatic habitats and water quality downstream.
Type of air pollution coul cause corrosion is dirt
The dam itself causes no pollution but the submerged vegetation in the reservoir behind the dam can decompose creating methane, a potent greenhouse gas. To prevent this it would be necessary to remove all vegetation and organic rich soil from the area proposed for the reservoir down to a clay base (or install a non-organic base).
They are a useful energy sourceThey cause no pollution when producing energyThey are expensive to build
dams cause many fishs' life cycle
Population could be considered a cause of pollution because the more people there are, the more waste produced and resources used, causing pollution. But no, it is not a type of pollution.
no
yes

Polluted water can causes the out brak of Jaundice.
No, wind does not cause pollution
Habitat loss, overfishing, building of dams and pollution.
It means that it doesn't cause pollution, or not much.
